Physics-informed reinforcement learning via probabilistic co-adjustment functions

no code implementations11 Sep 2023 Nat Wannawas, A. Aldo Faisal

Reinforcement learning of real-world tasks is very data inefficient, and extensive simulation-based modelling has become the dominant approach for training systems.

Towards AI-controlled FES-restoration of movements: Learning cycling stimulation pattern with reinforcement learning

no code implementations17 Mar 2023 Nat Wannawas, A. Aldo Faisal

By using just 100 seconds of cycling data, our method can deliver a fine-tuned pattern that gives better cycling performance.

Towards AI-controlled FES-restoration of arm movements: Controlling for progressive muscular fatigue with Gaussian state-space models

no code implementations10 Jan 2023 Nat Wannawas, A. Aldo Faisal

Yet, one remaining challenge of using RL to control FES is unobservable muscle fatigue that progressively changes as an unknown function of the stimulation, breaking the Markovian assumption of RL.

Towards AI-controlled FES-restoration of arm movements: neuromechanics-based reinforcement learning for 3-D reaching

no code implementations10 Jan 2023 Nat Wannawas, A. Aldo Faisal

In combination, our customisable models and RL-based control method open the possibility of delivering customised FES controls for different subjects and settings with minimal engineering intervention.

Neuromuscular Reinforcement Learning to Actuate Human Limbs through FES

no code implementations16 Sep 2022 Nat Wannawas, Ali Shafti, A. Aldo Faisal

Functional Electrical Stimulation (FES) is a technique to evoke muscle contraction through low-energy electrical signals.

I am Robot: Neuromuscular Reinforcement Learning to Actuate Human Limbs through Functional Electrical Stimulation

no code implementations9 Mar 2021 Nat Wannawas, Ali Shafti, A. Aldo Faisal

However, an open challenge remains on how to restore motor abilities to human limbs through FES, as the problem of controlling the stimulation is unclear.
